The ultrasonic distance sensor (ULS) described is a high-performance device with an enclosed waterproof probe. It operates on the principle of ultrasonic echo ranging, measuring the time between sending a pulse and receiving its echo to determine distance without contact. The sensor can detect materials and objects, including transparent or non-ferrous items, metals, non-metallic objects, liquids, solids, and powders. Its unique bell-mouth shell enhances ultrasound directivity and stability.

Features:

1. High Degree of Protection: The sensor is enclosed in a waterproof probe, protecting against environmental elements.
2. Wide Power Supply Range, Low Power Consumption: It can operate within a voltage range of 5V to 12V while consuming minimal power.
3. High Measuring Accuracy and Resolution: Offers precise distance measurements with a resolution of 1mm.
4. High-Precision Temperature Output and Compensation: Includes temperature output and compensation functions for enhanced accuracy.
5. Great Output Compatibility: Supports both RS232 and voltage analog output modes, providing flexibility in connectivity.
